The channels of disorder–order phase transitions through which there can arise orthorhombic (space group Pbcn) β'W2C, rhombohedral (space group ) β''W2C, and trigonal (space group ) εW2C superstructures of the disordered lower hexagonal carbide βW2C have been determined. The distri bution functions of carbon atoms in the superstructures under consideration have been calculated, and the physically admissible sequence of transformations associated with the ordering of the lower carbide βW2C that occur with a decrease in the temperature has been established.
